an anyone tell me how to determine the presens a/b when there are no disks in the drive (i.e. door open). INT 13, function 04H appears to work on IBM PC and XT, but is flaky on ATs. I've written a utility which needs to look at all valid logical drives to print a table of space available/utilization, however I'ld like to include drives A & B in this search and can't figure out how to do this for AT type machines reliably.
